To all whom it may concern: i

Be it known that-I, J oIrN HOWARD WAY, of Philadelphia, in the county ofPhiladelphia and State .of Pennsylvania, have in vented certain new anduseful Improvements in Concealed or Invisible Butt-Hinges,

whereof the following is a specification, reference being had to theaccompanying'drawily invention relates to butt-hinges of the concealedor invisible type, such as are commonly used for swinging the doors ofcoaches or automobiles. Such hinges comrise a fixed member, the butt ofwhich is recessed so as'to form a housing to receivo the pintle and theprojecting portion of the movable member. The pintle being I carried inthe housing is thus effectually concealed. My invention has to do wit 1means for securing ready adjustment of the pintle ofsuch a hinge withinthe housing, whereb the door which is thus swung may be ma e to morequickl and accurately fit between itsjambs or pil ar posts. To this endI provide-a readilyaccessible and easily actuated screw adjustmentbetween the recessed butt or member of the hinge and its .pintle.

In the accompanying drawin s, Figure I,

is a sectional view of butts em odying my invention.

Fig. II, is a sectional view of the face of the rccessedmember, and

'. Fig. III, a cross sectional view showing both members.

Fig. IV, is a Vie similar to Fig. 1, of

secured by screws to ceivethc adjustableca'rrier plate 4, which tion,and

bin e arm 11, an

Figs. V, and VI, are views similar-to. Figs. II, and III, of saidvariation,

'Referringto Fig. I,'the recessedfbutt of my hinge comprises the pillarpost. This plate. is provided-with a recess 2, which forms the housingwithin which the pintle is concealed. The pillar'postplate has furp r ythe ad ustable carrier plate with the plnlle ther-formed within itseats3, 3, which recarries the p ntle, and comprises wings 5, 5, offsets 6,6,a back plate 7, and a pintle 8, mounted between the oflsets.

The movable'butt com iririses the face plate 10, let into the ed e of te door, the curved j the knuckle 12, through WlilCl'L passes-the pintle8; Y

jA. diflicuity constantly experienced with a pillar post plate 1, I

butt hinges of this type has been the im-. possibility of securing anadjustment or read ustment when the door'binds in'its seat. It is theobject of my invention to provide a readily accessible and quicklactuated. ad ustment to overeome this di culty. To this'end theadjustable carrier plate I, is attached to its seat by means ofadjustment screws 20, 20. The head of each screw is held in fixedrelation to the carrier plate by means of the enlarged head 21, and thecollar 22, forming shoulders which rotate against the two surfaces ofthe carrier plate. The threaded portion of each screw s cccived within athreaded aperture 23, in the pillar post plate. .liy turning thesescrews the adjustable carrier plate may be thrust in or out of its seatin the pillar post plate, carrying with it the pintle, and thus therequired adjustment 15 secured. The head of each of these adjustmentscrews 20, is let into the visible surface If the'adjustable carrierplate, but otherwise is-directly accessible and can be turned, by anordinary screw driver whenever the door which swings upon the hinge isopen. I

In thevariation of my invention shown in Fig. IV, the parts are thesame, except for the means for securing the adjustment. In this case asingle screw 25, with enlarged head 26, and collar 27.,rotates withinthe back of the adjustable carrier late, its

threaded end being received within the is received and concealed; andmeans for adjusting the depth to which said adjustable carrier plate,and consequently the pintle, is received within the housing.

2. In a concealed hinge, the combination of an adjustable carrier platecarrying the pintle of the hinge; a houslng within which the adjustablecarrier plate with the pintle' is received and concealed; and one ormore screws constitutixigthe petmjinent yenia", this twenty-fourth dayof September, I tion between the adjusthble plate 1917. and the housing,and by turning whlch the relation between the pintle and the J OHNHQWARD WAY.
